Full Sharh — Sahih al-Bukhari 6562
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ رَجَاءٍ، حَدَّثَنَا إِسْرَائِيلُ، عَنْ أَبِي إِسْحَاقَ، عَنِ النُّعْمَانِ بْنِ بَشِيرٍ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " إِنَّ أَهْوَنَ أَهْلِ النَّارِ عَذَابًا يَوْمَ الْقِيَامَةِ رَجُلٌ عَلَى أَخْمَصِ قَدَمَيْهِ جَمْرَتَانِ يَغْلِي مِنْهُمَا دِمَاغُهُ، كَمَا يَغْلِي الْمِرْجَلُ وَالْقُمْقُمُ".
English Translation
Narrated An-Nu`man bin Bashir:I heard the Prophet (ﷺ) saying, "The least punished person of the (Hell) Fire people on the Day of Resurrection will be a man under whose arch of the feet two smoldering embers will be placed, because of which his brain will boil just like Al-Mirjal (copper vessel) or a Qum-qum (narrow-necked vessel) is boiling with water
